CALENDAR.

SPECIFICATION forming partof Letters Patent No. 284,270, dated September 4, 1883.

Application filed Mmh 30,1883. (No modeLl- To all whom it may concern to anyparticular year-it being the object of the-invention to provide a calendar of this description which shall be simple in construction, reliable in operation, present an attractive and ornamental appearance, and which can be produced at a very trifling expense. To these ends the invention consists in certain details of construction and combinations of parts, to be hereinafter fully described and particularly pointed out.

In the accompanying drawings, Figure 1 is, a plan view of a calendar embodying the in vention, certain of the parts being broken away for the sake of clearness of illustration. Fig. 2 is a cro ss section of the same, taken upon the line :0 x, and Fig. 3is a plan view of the month card or disk.

Referring to saidfigures, it will be seenthat the principal parts of the structure consist of Q a plain card or disk, 8, having arrangedaround its edge a row of figures or characters indicat ing the days of the month, and an annular card or disk, 9, having arranged around its edge in like manner. the names of the months of the year, these two being inclosed in a suitable ca'sing, 10, the face 12 of which is provided with sight-openings 13 14, through which the figures and names indicating the days and months are successively exposed as the cards are rotated. The card or disk 8 is supported upon a small shaft or stud, 7, which passes through the center of the card, and has its inner end supported in a pivotal bearing in a block, 17, rigidlysecured to the backof the casing, while its opposite end extends a through the front of the casing and terminates in a knob or button, 15, by which the stud can be conveniently rotated. The card 8 is secured to the stud 7, so as to rotate therewith,

" in any convenient manner, as by the laterallyprojecting pin 6, which passes through a loop, 5, attached to the rear side of the card. The annular card 9, which carries the names of the months, is supported in the casing beneath or back of the card 8, but is placed eccentrically thereto, so that at one point of its revolution its edge is caused to project beyond the edge of the card 8, thereby permitting the names of the months to be exposed through the opening 14, as shown in Figs. 1 and 2. In order that boththe day and month cards may be operated by the same instrumentality, and the latter be always shifted at the proper time without the performance of an extra operation, it is provided with a backwardlyextending rim or flange, 4, in which are formed a series 1 of. openings, 3, corresponding to the names of the months upon the face of the card, the rear edge of said rim being in turn connected to a second annular card, 16, the inner periphery of which rests in a recess formed between the back of the casing 10 and the rabbeted edge of the circular block17. The stud 7 is provided with an arm, 1, which at each revolution of the stud passes into one of the openings, 3, and comes into engagement with its forward wall, 2, thereby turning the card 9 r one step and bringing the name. of the next month into view. The operation of the apparatus is as follows:

Assuming that the parts are in the position shown in Fig. 1, the stud 7 will be turned step by step, bringing the numbers of the days upon the card 8 successively into view through the opening 13, until the last day of the month is reached, at which time the arm 1 will be at or near the position indicated by the dotted lines in Fig. 3. As the stud is turned to advance the card 8, so as to expose the number for the first day of the next month, thearm 1 will be advanced to the position shown in Fig. 1, and during such advancement it will engage with oneof the walls 2 and advance the card 9, so

as to expose the name of the next month, as shown in said figure, and so the operation will be repeated, the card 9 being advanced one step for each revolution of the card 8. At the end'of those months in which there are less than thirty-one days the card 8 will of course be advanced two, three, or'four steps, as the case may be, at once.

The casing 10 and the other principal parts of the calendar will usually be composed of card or paste board; but any other suitable or desirable material maybe employed.

The casing 10 may be provided with any suitable means for suspending the calendar upon the Wall of a room, or with an easel-leg or other suitable means for supporting it in an upright or inclined position upon a desk or table.

The face 12 of the casing may be provided 7 with suitable ornamentation to give the calendar an attractive appearance; or it may bear any desired advertising matter.

What I claim is- 1. The combination, with the casing 10, of the rotating disk8 and the annular rotating flanged disk 9, having openings, and mounted eccentrically thereto and operated by an arm, as 1, extending from the stud of the disk 8,

substantially as described. 20
